Title: Tyre Wear (average?)
Post by: Anonymous on June 24, 2004, 10:30
Have done quick search but couldn't find details of average tyre wear.

The susp etc is standard and i have driven 11 500 miles.

The inside edges of the front tyres are almost bald   s:shock: :shock: s:shock:   (meant to wear like that accordin to one of the searches) and the rear inside's seem to be almost illegal also.

is 11,500 miles average?

Of the 2 sets I've now been through, they wore absolutley evenly across the width of the tyre, and lasted about 15,000 a set. Although I will point out that by that time they were very illegal...

I thought the inside fronts wore quicker because of the camber setup of the car?

If not then this might give some insight into the steering problems i have been having along with the creaking (booked in for Monday)

Camber settings will effect the tyre ware of the car. How much tred is on the rest of the tyre?

As standard the neg camber on the car is minimal, (less than 1 deg IIRC, its been a while  s:wink: :wink: s:wink:  ) so wear should be fairly even. My cars had an alignment check every 6 - 8 months since it was a year old and I've always worn the tyres absolutley evenly.

I'd say about 5mm on the outside (front) and almost completely bald on the inside.

Maybe (4mm) outside rear and again almost completly bald on the inside!

Had the tracking checked about 6 weeks ago and it was fine!!

Tracking is only a small sub-set of a full geom check. Depending on the wear pattern, you either have a camber or toe setting out of alignment.

I've had tyres last from 1,200 (!) miles to about 10,000 depending on usage, typically closer to 10,000 for the fronts and around 7,000 for rears.

If you remember these posts:

 m http://www.mr2roc.org/forum/viewtopic.p ... highlight= (http://www.mr2roc.org/forum/viewtopic.php?t=3837&highlight=) m

I asked Mr-T to look at the tracking and do a check and it all came back fine and they just blamed it on having 1 new tyre and 3 slightly older ones.

I am now at the stage or replacing the older ones - as i raised the point with them do you think its worth asking for a contribution toward the cost as its something they should have sorted?

i must be a right boring driver then, i've done 12,500 and still got a minimum of 5mm left, 7 on one of the fronts  s:? :? s:?

stock bridgestones by the way

This is an interesting thread in that the inside edge of my fronts (Stock Bridgies) are also wearing, although I have much higher milage on my tyres than most (don't know why, but even with agressive driving, my tyres have lasted 25K!!!!  s:shock: :shock: s:shock:  I think it is cos I also doa lot of motorway driving too......). I was also told that the geometry was out, but the car handles lovely and the wear, in my eyes, is not excessive. I am looking to get the Toyo's put on in the next month or so, so I was wondering if people reckon it was worth me getting an alignement done to stop this kind of wear happening on the new tyres? I had one done on it not long after I had the car (about a year ago when it was done now). How much is it likely to have changed in that time?

interesting that you said about most of your driving being done on motorways John, same for me, probably about 9000 out of the 12500, just goes to prove that motorways are better for tyres, boring though  s:? :? s:?
Title:
Post by: Anonymous on June 24, 2004, 12:10
Yeah, I tend to do most of milage, unfortunately, on motorways, probably about the same amount as you. But when I DO get off the M-Way and get a chance to actually drive the car, I do give us some, so its not as if I am looking after them in the correct way, yet I am only just coming to the end of their life after 25K. Strange that innit?

I've done 11K and got plenty on my stock Bridgestones. I do a lot of motorway mileage and always give it some around the windies. I guess they are a harder compound. Phil what did you get from yours  s:?: :?: s:?:

Yes, if you keep driving straight  s;) ;) s;)

Start taking those turns with a nice pace and you'll get even tyre wear as a bonus  s;) ;) s;)

20,000 miles 3 sets of rears, 2 sets of fronts.  'spirited' driving style.

It's one of the reasons I'm not tracking it any more.  A bit of a comparison for you:

A full set of Yoko novas for the Mr2 = £400
A full set of part worn slicks for the PPE = £80
Title:
Post by: Anonymous on June 24, 2004, 14:52
Yep, can see why!!!!  s:shock: :shock: s:shock:    s:shock: :shock: s:shock:  

Suppose if you have the PPE though its not such a big loss........
Title:
Post by: juansolo on June 24, 2004, 15:14
Indeed.  I'd always prefer to be on track in the PPE regardless of the weather.  It's just the faff either side and the trailering that can be a bit of a drag compared to just getting in the Mr2 and going.  Though I've been on a faff reduction drive of late.

PPE not going to help then is it?!!!  s:wink: :wink: s:wink:    s:lol: :lol: s:lol:

Ok - don't take this the wrong way as i might be sounding daft here but.....I understand the speed you take a corner at would mean they last longer but can it make them wear differently/
Title:
Post by: markiii on June 24, 2004, 17:48
at a push yes.

the faster you go around teh corner the mor weight transfer to the outside tyre, so if you did a lot of fadt left hand bends in theory the right hand rear tyre would wear more.

Just wait until I lose my temper with it next.  Seems to happen about once every 12 months or so when I break something really expensive.

Yeah, think of it this way. Negative camber means the wheels are a bit like this:
//CAR\ (I'm sure you knew that, it's just easier to explain with a pic  s8) 8) s8) )

So most of the cars weight is on the inside edge of tyres. Now if you keep driving straight, it will only wear the inside edge. If you take a corner at low speed, it's still the same. But when you take a corner at "proper" speed, the weight shifts outwards, the suspension does its job and the wheel turns like this:
//CAR|| (when taking a fast left corner)

And that's how you get even wear with fast cornering  s;) ;) s;)

And the lesson learnt Bigun is start to get a few more windies in at high speed  s:wink: :wink: s:wink:

so let me get this right

motorway driving = less wear = dont change tyres so much = more money for other mods  s:twisted: :twisted: s:twisted:  

unfortunatley also = boring!  s:evil: :evil: s:evil:

Well she's gone in today to have the strut top mounts replaced, the leather on the door cards re-applied, the fuel gauge checked, the scuff plates re-applied and to check the tyre wear.

Just a small list  s;) ;) s;)
